BOILER.

Specification of Letters Patent No. 25,511, dated September 20, 1859.

T 0 all whom it may concern:

Be it known that I, CHRISTIAN Kmrrnn, of Lancaster city, county ofLancaster, and State of Pennsylvania, have'invented new and usefulImprovements in Calorific Boilers; and I do hereby declare that thefollowing is a full and exact description thereof, referencebeing had tothe accompanying drawings, and to the letters of reference markedthereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof extension and perforated pipes and frying pan with side pipes.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents the boiler, in which the water is kept boiling regularly,by the extension hot-air-fiue or pipe B, and the extension andperforated steam pipe C, leading from the furnace D, across the bottomof the boiler, and upward along the side. The furnace D, contains asmall charcoal fire cylinder, within a cylinder containing water, thewater being in the space E, between the fire cylinder, and concavecylinder of furnace D.

F, is the door and opening through which the fuel is put into the firecylinder; G, the pipe leading from the water cylinder E into the bottomof the boiler A.

H is the frying pan located above the furnace D for baking or fryingmeats or vegetables. This pan H has two flues I-I- one at each end.

J represents a smaller boiler at the side of main boiler A, having aperforated pipe K extending from the main boiler across the bottom ofthe small boiler J, and half way upward along the side.

L, L, L, are kettles With perforated bottoms, and apertures M throughwhich the pipe or hot air flue B passes out above. The kettles slideinto and fit on each other and are for cooking purposes for all kinds ofvegetables and fruits, and the cooking is done by the steam from themain boiler A passing through the open bottoms of the kettles.

IVhen the fire is kindled in the furnace D the heat passes upward andout of the fines or pipes I, and the lid N of flue B is placed over thetop of the flue. After the draft and fire begins to heat, then the lid Nis taken off the pipe B and the lids P are placed over the pipes I, I.The pan H is then heated ready for frying meats &c., and the heatlikewise passes from the furnace through the hot air pipe B across thebottom of the main boiler A and upward through the kettles, which keepsthe water at a regular boiling heat. The perforated steam pipe C alsoextends across the boiler and upward to assist in keeping the waterboiling. The pipe G extending from the water in cylinder E is thefeeder, and when the water in cylinder E becomes heated, then the coolwater in pipe G is passing from the main boiler A to the furnacecylinder E and is there heated, and passes off into steam through thesteam pipe G into the boiler A.

The advantages are the saving of fuel, and economy in price.

I do not claim a feeder or connecting steam pipes from the furnace tothe boiler, as they have been used; but

hat I claim as my invention, and desire to secure by Letters Patent isThe construction of the extension and perforated steam pipe C, vith theextension hot air flue B the pan H with pipes I, I and perforated pipe Karranged and combined, substantially as herein described, and for thepurposes set forth.

CHRISTIAN KIEFFER.
